Font loading only when logged in to Hubspot

Hi guys,
I’m facing a weird issue with font loading.
My landing pages are loading the Proxima-Nova font but they seem to display it only to hubspot logged in users. Anybody looking at the page and not logged to Hubspot (i.e. the whole world) see a different font, which is a big problem to me.
I tried with different computers, versions of Chrome, cleared browser cache, no luck.
Example here: http://get.myfeelback.com/en/maisons-du-monde-en
Below is the version when logged and displaying the right font :

And here is the version everyone sees with the wrong font (serif):

My template mentions this:

And the MyFeelBack_Nov2015-fonts.css file mentions this:

Can you help, please?
Thanks,

@jeromecollomb it looks like the font files are 404’ing in the console. You may want to upload the font files again and relink them.

P.S. random performance tip: move the CSS to your global head and use the {{ require_css() }} HubL function instead of using CSS @ imports. This will increase your page speed since it will be able to asynchronously load the CSS files.

How could I miss this?
